Here is my Jurassic collection from the Morrison formation. This is a collection I really want to expand so if anyone has any fossils from the Morrison they'd be willing to trade definitely message me. the latest addition to my Morrison formation collection is the large partial Allosaurus vert my parents got me for Christmas. The fossil in the bottom right of the first pic is a chunk of bone, probably Camarasaurus. The fossil in the top right of the first pic is a chunk of bone, probably theropod.

Hey everyone. I purchased this fossil recently and wanted to get your opinions on it. It is from the Hell Creek formation of Montana. The seller says that is either a surangular or angular bone from a theropod jaw. After looking at pictures it does look very similar to the angular bone of a Nanotyrannus, looks about the right size too. What do you dinosaur experts think? Thanks!
